Problem (2)

In the Bohr model of the hydrogen atom, the speed of the electron is approximately 2.20 × 106 m/s. Find
(a) the force acting on the electron as it revolves in a circular orbit of radius 0.530 × 10-10 m
(b) the centripetal acceleration of the electron.
(((mass of electron=9.1×10-31 kg)))
